The spatiospectral characterization of brain networks: Fusing concurrent EEG spectra and fMRI maps

David A. Bridwell, Lei Wu, Tom Eichele, Vince D. Calhoun
2013 NeuroImage  
We examined the correspondence between intrinsic fMRI and EEG network activity at rest in order to characterize brain networks both spatially (with fMRI) and spectrally (with EEG).  ...  Brain networks were separately identified within the concurrently recorded fMRI and EEG at the aggregate group level with group independent component analysis and the association between spatial fMRI and  ...  This research was supported by National Institute of Heath grants NIBIB 1R01EB006841 and NCRR 5P20RR021938.  ...

Fusing Concurrent EEG and fMRI Intrinsic Networks [chapter]

David Bridwell, Vince Calhoun
2014 Magnetoencephalography  
The resulting EEG-fMRI networks capture a broader range of brain dynamics compared to EEG or fMRI alone, and can serve as a reference for studies integrating MEG and fMRI.  ...  The following chapter surveys the physiological differences between EEG and fMRI recordings and the implications and results of their integration.  ...  Fluctuations in ERP and fMRI maps across subjects may be directly compared with results from MEG, which can further improve the ability to spatiotemporally characterize brain activity (Plis et al. 2010  ...
